Title
Description
In this talk, we'll generally explore the static type eco system in Ruby. Ruby has two main type checkers Sorbet and RBS. Sorbet was created by the Stripe and RBS is supported by ruby. Sorbet is an annotation base type checking system while RBS is a definition file-based type system. We'll add type annotation for a popular gem using sorbet and RBS and then compare the differences between the two systems. There is lot of interoperability announced between Sorbet and RBS and we'll explore if it's practically possible to convert a sorbet annotated project to RBS.

In this talk, Gaurav Kumar Singh explores static typing in Ruby using RBS at RubyConf 2022. He starts by defining the concepts of static and dynamic typing, explaining the issues associated with dynamic typing through examples in Java and Ruby. The main challenges of dynamic typing include runtime errors and the limitations of thorough testing. To address these, Singh introduces static typing as a way to catch errors early and improve code quality. Key Points Discussed: - **Static Typing vs. Dynamic Typing**: Static typing defines variable types at compile-time (e.g., Java) while dynamic typing determines types at runtime (e.g., Ruby). - **Advantages of Static Typing**: It helps in eliminating runtime errors, enhances IDE integration, and improves documentation through type annotations. - **Overview of Ruby's Type Checkers**: Singh discusses the evolution of type checkers in Ruby, including Diamondback Ruby, RDL, Sorbet, and RBS, which was introduced by the Ruby core team in 2019. - **Understanding RBS**: RBS (Ruby Syntax) functions as a type definition file system rather than checking code types directly. It helps define the structure of Ruby code and can be generated using various methods like RB, RBI, and runtime. - **Creating RBS Files**: Through a 'User' class example, Singh demonstrates how to generate RBS files and define types for class attributes to catch early errors. - **Dynamic vs. Static Attributes**: He explains the nuances of generating RBS for dynamically defined attributes and methods, suggesting that runtime options might be more effective for such cases. - **Function Signatures in RBS**: Various function examples illustrate how to use optional arguments, splat operators, union types, and keyword arguments. - **Introduction to Steep**: Steep is mentioned as a tool for type-checking RBS code against Ruby, highlighting its capabilities for providing code coverage statistics and error management. - **Interoperability of Sorbet and RBS**: Singh concludes by discussing the differences between Sorbet and RBS, emphasizing the annotation-based nature of Sorbet compared to RBS's definition file approach. Despite their differences, both systems can improve type-checking in Ruby. The talk concludes with the affirmation that the adoption of tools like Sorbet and RBS can significantly enhance Ruby's type-checking capabilities, improve code robustness, and facilitate code management.
